Hand stamp

Filed NOV. 15, 1955 Patented Mar. 17, 1936 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to improvements in hand stamps. It consists of a one-piece holder for stencils and inkpads.

'I'he object of my invention is to provide novel means for obtaining impressions from typewritten or hand-made stencils of the smallest dimensions as well as from stencils of` larger size.

One form of the invention is illustrated in the accompanying drawing, in which Fig. 1 is a vertical section of the stencil holder, Fig. 2 a perspective view of the stencil holder, and Fig. 3 a perspective view of the stencil holder with inkpad and stencil att-ached for printing.

A perforated base or diaphragm I, with grooved sides 2 2, integral with a handle 3, is formed from one piece of material into a hollow stencil holder with open ends, through which ink may be applied to the upper and inner surface of ,diaphragm I, and through its perforations to an inkpad 6.

In arranging my device for printing, an inkpad 6 the exact size of the base of diaphragm I is applied to the base of diaphragm I. A stencil 4, which is wider than diaphragm I, is applied over and outside the inkpad. The surplus width of the stencil 4 is brought up over the grooves 2-2 and secured in place by a resilient rub-ber or other band 5 which ts over the stencil 4 in the grooves 2 2. No individual fastening is provided for the inkpad 6 which is effectively held in position by the superimposed stencil 4.

In dispensing with clamps for securing the inkpad to the diaphragm, and other clamps for holding the stencil in place, and employing instead only one resilient cincture 5 for positioning and securing the stencil, I attain the utmost simplicity and economy of mechanism and space. My method of securing the stencil, combined with the hollow one-piece construction of the stencil holder, adapts the stencil printing process to hand stamps as narrow as one line in width and of any desired length.

The parallel longitudinal grooves of the sides 2 form inwardly projecting ribs on each side o-f (Cl. lill-125) the diaphragm of the casing, thereby giving the diaphragm strength and rigidity. Additional strength is obtained by running the handle 3 longitudinally of the casing I from one end of the same to the other. quadrilateral design of the handle 3 of the same length as the casing with which it is integrally connected, assures perfection of control of the hand stamp and registration of the stencil with the paper as the stamp is used. The handle comfortably fits.` the hand of the user and eliminates any possibility of tipping of the stencil as pressure applied to the handle is directed evenly over the .entire length of the casing I. Accurate and clear cut impressions from the stencil are thus always obtained.

No improvement is claimed in the familiar process of printing through a stencil superimposed upon an inkpad supported by a rigid perforated diaphragm.

Hand stamps employing the stencil printing process are in common use. I therefore do not claim such a combination broadly; but

I claim:

A hand stamp comprising a single strip of sheet material forming a casing, said strip being curved and perforated to form a diaphragm bottom, the outer surface of which forms portions of the surface of a cylinder, said strip being bent upwardly at the two side edges of said bottom and forming upright grooved side walls extending therefrom, the portions of said strip .of material above said side walls being bent rst in- Wardly and then upwardly to form a handle eX- tending from one end to the other of the casing and substantially in a plane parallel to the central longitudinal axis of said cylinder, an ink pad underlying said bottom and a stencil underlying said pad and including upturned sides abutting said side walls and means received within said grooves and bearing against the sides of said stencil and holding the same in place.

IRVINE. INNES.
